I have Sabre board(MCIMX6SX-SDB) from NXP, now require full source code or link to download

Hi, I have Sabre board(MCIMX6SX-SDB), with this only bootable images but i don't not full source code. So we require the full source code which include toolchain and A9 and M4 source to compile and build. Please share the source also related links.

Please follow the Yocto User’s Guide document contained in this bundle. Since Yocto is used as a means of distribution the source code is fetched on demand. You may, however, fetch the required sources for a given image by using the following command:

bitbake <image_or_recipe> -c fetchall

You may also extract the toolchain using:

bitbake meta-toolchain

Once fetched you can find the source code on the work directory:

/<BSP_DIR>/<BUILD_DIR>/tmp/work/

For example, the source for the kernel would be on:

/<BSP_DIR>/<BUILD_DIR>/tmp/work/<MACHINE>/linux-imx/<KERNEL_VER>/git/

The sources are located depending on the recipes that compiles and install the packages so it may not be very straightforward.
